【摘要】：燃气作为一种清洁、高效、优质的能源，在如今城市工业生产和居民生活中占有举足轻重的地位，因此我国的城市燃气行业正处于蓬勃发展阶段。但燃气本身有毒、易燃、易爆的特性，再加上城市燃气管网一般敷设于人口稠密、经济集中的区域，一旦管道发生破裂、出现燃气泄漏，将会造成中毒、火灾和爆炸等恶性事故，给城市居民的生命财产带来重大损失，，同时也会在社会上造成深远的不良影响。因此，对城市燃气管网进行风险管理，将城市燃气管网的风险管理模式从事后管理模式转变为事前管理模式，制定相应的预防、维护和管理措施，提高城市燃气管网运行的安全性和可靠性是十分必要的。风险管理包括风险辨识、风险评价和风险控制。本文运用故障树分析法对东营市城区燃气管网管道失效的风险因素进行辨识，建立起东营市城区燃气管网风险评价的指标体系，在此基础上，运用管道指数评分法对燃气管网进行风险评价，这种方法考虑了一旦燃气发生泄漏对周围环境和人员的影响，其结论的可信度较高。最后，结合风险评价的结论和东营市城区燃气管网中出现的问题，提出了有针对性的、旨在于提高东营市城区燃气管网的安全性和可靠性的风险管理措施。
[Abstract]:As a kind of clean, efficient and high quality energy, gas plays an important role in the urban industrial production and residents' life. Therefore, the city gas industry in our country is in a booming stage of development. However, the gas itself is poisonous and flammable. Explosive characteristics, coupled with the fact that urban gas networks are generally located in densely populated and economically concentrated areas, once the pipeline breaks and gas leaks occur, it will lead to toxic, fire and explosion accidents. It will bring great loss of life and property to urban residents, and will also cause far-reaching adverse effects in society. Therefore, risk management of urban gas pipeline network will be carried out. It is necessary to change the risk management mode of urban gas pipeline network from the post management mode to the prior management mode, to formulate the corresponding prevention, maintenance and management measures, and to improve the safety and reliability of the urban gas pipeline network operation. Risk management includes risk identification, risk evaluation and risk control. The risk evaluation index system of gas pipeline network in Dongying city is established. On this basis, the pipeline index scoring method is used to evaluate the risk of gas pipeline network. This method takes into account the impact of gas leakage on the surrounding environment and personnel. The reliability of the conclusions is high. Finally, combining the conclusions of risk evaluation and the problems in the gas pipeline network of Dongying City, the paper puts forward some pertinence, In order to improve the safety and reliability of Dongying city gas pipe network risk management measures.
